It copies a portion of a Java array into a buffer that you supply. >Can I use this function to copy some elements from the C array to the >Java array? No, you should use SetByteArrayRegion for that. You could, of course, use GetByteArrayRegion to copy a portion of the Java array into a buffer, modify some of the bytes, and then use SetByteArrayRegion to copy the whole thing back to the Java application. >Should I call the release-function afterwards? No. -Steve
